Thanks, But don't find the some examples in source tree of NM in examples directory.
Also I still have the confuse for the connection
I have the object path /org/freedesktop/NetworkManager/Devices/0 for
WIFI under the bus name org.freedesktop.NetworkManager, and
/org/freedesktop/NetworkManager/AccessPoint/15 for this connection

$SERVICE="org.freedesktop.NetworkManager"
$CONNECTION="/org/freedesktop/NetworkManager/AccessPoint/15"
$DEVICE="/org/freedesktop/NetworkManager/Devices/0"
$ dbus-send --system --print-reply --type=method_call
--dest=org.freedesktop.NetworkManager /org/freedesktop/NetworkManager
org.freedesktop.NetworkManager.ActivateConnection string:"$SERVICE"
objpath:"$CONNECTION" objpath:"$DEVICE" objpath:"/"

Error org.freedesktop.NetworkManager.InvalidService: Invalid settings service name


If I try the following, it also have the errors:

SERVICE="org.freedesktop.NetworkManagerSystemSettings"
 CONNECTION="/org/freedesktop/NetworkManager/AccessPoint/15"
 DEVICE="/org/freedesktop/NetworkManager/Devices/0"
 dbus-send --system --print-reply --type=method_call
--dest='org.freedesktop.NetworkManager'
'/org/freedesktop/NetworkManager'
org.freedesktop.NetworkManager.ActivateConnection string:"$SERVICE"
objpath:"$CONNECTION" objpath:"$DEVICE" objpath:"/"
 
Error org.freedesktop.NetworkManager.UnknownConnection: Connection was not provided by any settings service

How can I solve this problem? Thanks

You are looking for ActivateConnection method of
org.freedesktop.NetworkManager interface:
http://projects.gnome.org/NetworkManager/developers/spec-08.html#org.freedesktop.NetworkManager

When connecting, NM uses a concept of connections, which are configured profiles
that can be activated on a device.
For more info see http://live.gnome.org/NetworkManagerConfiguration

Here are two simple examples, how to activate a connection. You have to adjust
the paths of course.
1) Python
#!/usr/bin/python

import dbus

SERVICE = "org.freedesktop.NetworkManagerSystemSettings"
OPATH = "/org/freedesktop/NetworkManager"
IFACE = "org.freedesktop.NetworkManager"
CONNECTION = "/org/freedesktop/NetworkManagerSettings/1"
DEVICE = "/org/freedesktop/NetworkManager/Devices/0"

bus = dbus.SystemBus()
nm_iface = dbus.Interface(bus.get_object(SERVICE, OPATH), IFACE)

# Ask NM to activate the connection
active_path = nm_iface.ActivateConnection(SERVICE, CONNECTION, DEVICE, "/")
if not active_path:
   print "Couldn't activate connection"
   sys.exit(1)

2) Bash
#!/bin/bash

SERVICE="org.freedesktop.NetworkManagerSystemSettings"
CONNECTION="/org/freedesktop/NetworkManagerSettings/1"
DEVICE="/org/freedesktop/NetworkManager/Devices/0"

dbus-send --system --print-reply --type=method_call --
dest='org.freedesktop.NetworkManager' \
'/org/freedesktop/NetworkManager'
org.freedesktop.NetworkManager.ActivateConnection \
string:"$SERVICE" objpath:"$CONNECTION" objpath:"$DEVICE" objpath:"/"


You can also find some examples in source tree of NM in examples directory.

We should probably create a section on wiki with some examples to have them in
one place and easy to find.
